Arnold & Son has given its signature skeleton watch a solid gold guilloche case back that forms a decorative backdrop for the unusual pyramid-shaped movement.
A red gold case back, decorated with guilloche on both sides, highlights the unusual skeleton movement of the Arnold & Son Time Pyramid Guilloché. Originally introduced two years ago, the Time Pyramid is a skeleton watch with the movement modelled on 19th century English skeleton clocks. The Time Pyramid Guilloché is equipped with the same skeleton movement, but instead of a clear sapphire rear it has a red gold case case back. The front facing side is decorated with a sun ray guilloche, while the reverse is finished with a barleycorn engine turning of the sort common on pocket watches. The case is red gold and 44.6mm in diameter.
Case back aside the Time Pyramid Guilloché is identical to the original, with an in-house, hand-wound movement laid out like a pyramid. The escapement sits at the apex of the pyramid, with the gear train running linearly downwards to the twin barrels at four and seven o’clock. It has a 90 hour power reserve, along with twin power reserve indicators at three and nine o’clock for each barrel.
In recent years Arnold & Son has undergone a renaissance of sorts, consistently turning out interesting watches with proprietary movements like the Time Pyramid (also true for its newly launched brand Angelus). That thanks in part to La Joux-Perret, a movement constructor and manufacture, and along with Arnold & Son, owned by Citizen of Japan.
The Time Pyramid Guilloché is priced at SFr42,900.
